Good post, I relate to most of what you've mentionedThere are occasional times where I don't think anxiety is holding me back, but I still can't make conversation or connect with people because I have nothing in common with human beings....It seems like socializing requires giving up your identity and morphing into more of a shared cultural identity. It makes sense that there's a give and take, it's only fair, but I still can't bring myself to accept it.
To summarize it bluntly, normal conversations bore me to death and usually might as well be in a foreign language. So my chances of navigating the social maze to reach the people who can talk about things that I can talk about are rather slim.
